Best Mountain Park (2002)

For sheer accessibility and versatility, it's hard to beat Genesee Park, Denver's first -- and largest -- mountain park, just off of I-70 at Exit 254. Created between 1912 and 1937, this park has all the outdoor amenities, from grills to softball fields, as well as the most-gawked-at section: an elk and bison enclosure. Also noteworthy is the Braille Trail, with signs in Braille and waist-high guide wire.
